Aracer RC Mini 4C ECU


The RC Mini 4C ecu is a complete replacement unit for the keen tuner on a budget. It allows the user to change their ecu to an upgraded unit and apply their own custom tuning!


We strongly recommend tuning to be done by a professional tuning shop in order to make the most out of your bike. 


The four switches on the bike are as follows:

Channel A- Timing Adjustment: Advance or Retard spark angle in all range

Channel B- Needle Jet: Adjust for "overall" mapping

Channel C- Pilot Jet: Fuel Adjustments under 30%

Channel D- Main Jet: Fuel Adjustments over 70%
